In terms of 'broad inclusion, my slicer comprises a frame providing a journal for a guide roller and support for a cutting element. The guide roller is preferably conical in shape, and is slidably arranged on the frame so that the line of rolling contact is maintained parallel with the cutting element, whereby sliding the roller along its axis adjusts the thickness of slice. My present invention is directed primarily to improvements in the frame structure and mounting for the roller.

In greater detail, and referring particularly to Figures 1 to 3 of the drawings, the slicer embodying my invention comprises a frame shaped from heavy wire or rod material, and having a straight portion providing an axle 2 terminating at one end in a loop providing a handle 3. The end of the rod at the handle extends transversely across Cil 2. axle portion 2 to provide a tie arm 4 lyingsubi stantially ini the plane of the-'- handle-*"loolp. Another-tie Aarm 6 is?formed:at'the-opposite end of axle 2,1 preferably.' by bending' the fen'd of the? 1 rod outwardly-- tolie'in the directionof and-Sulci-` is preferably conical in shape,` andfcuttinglele* rnentfS-isvinclin'ed to the axi's'oftheirollerlso that the line" v(3f-rolling contact/fis' Iarlarldfpartlll Witl the cuttingE element.l Shiftin'gthe guide* rolleralongax-le 2 controlsthe;thicknessfofslicej" and this is facilitated by' graduations I 'Ost'alizfiped`1 on the axle. Shifting the'- roller't'ol 'thefleft' in"4 Figurel operates to increase' the thickness 'ofi slice, while shifting the rollerto therig-ht 'S'rvesf to decrease the thickness of slice: l

Since the line of rolling' contact-*is'iparallelto' the cutting elements thererisv little *tendency-*for the roller to shift laterally;` 'but '-'If preferto provideA means to holdthe roller'in'la' selected* position:l As' shown'inFigure A2j a`l core sleeve 9 lupoiwhich the roller"A is jo'urnaled is slidably mour'i'tedf ori"- axle 2. 'Ihe'sleeve'may b'ea-complete'tubeg orl drawn from a vflat 'sheet' witha" longitudinal slotK left between` adjacentedgesif Each end-*offthe:l sleeve has an axially extending'- "slotf' I I-' andan'` annular-groove1I2 lying across the-slot. Slots II1 extend through both walls of the sleeve; and groove I2 is preferably formed by rolling. Split collar I3 is seated in groove I2 at each end of roller l, and functions as a retainer for the roller and also as means for compressing the sleeve into frictional engagement with the axle. The slot and groove arrangement allows collar I3 to be readily slipped into seated position for convenience in assembly, and also provides for the desired frictional engagement between the sleeve and axle due to the compression of the sleeve when the collar is finally seated. The frictional engagement is preferably relatively light to allow free axial adjustment of the roller, since little force is required to keep the roller in adjusted position during operation of the unit.

As shown in Figure 3, cutting wire 8 is preferably fastened by wrapping say twice around the tie arm and then clamping the end of the wire in a slot I4 cut in the end of the arm. This method of tying the wire is simple and I have found it very eifective. When the cutting wire is applied it is put under suicient tension to insure that the Wire will be taut. In my improved frame structure there is additional assurance that the cutting element will be taut during operation of the slicer, because when an operator grasps the handle 3 the tie arms 4 and E tend to spread and thus further tension the cutting element.

Figure 4 shows a modified frame structure in which tie arm 4 is bent to lie at substantially right angles to the plane of handle loop 3. The other tie arm i6 is formed from a separate piece with an aperture press fitted on a squared end Il of the axle. Pointed ears I8 are also preferably provided on the end piece, extending oppositely from arm I6. These pointed ears provide a fork for picking up or moving the sliced material.

In the modification shown in Figure 5, a portion of the frame rod. extends back along the axle to form a bridge I9 terminating in a tie arm 2l extending transversely across the end of axle 2. This tie arm is also recessed to provide a socket for pointed end 22 of the axle, thus giving support for the latter. The portions of the rod between handle 3 and bridge I9 are preferably shaped into a loop 23 extending transversely of the axle to provide the other tie arm for cutting element 8. Loop 23 preferably straddles axle portion 2 for further rigidity; and it will be observed that tension in cutting element 8 tends to hold pointed end 22 of the axle in seated position.

In the modification shown in Figure 6 a separate handle 24, such as wood, is provided, and axle 2 terminates at one end in a pointed tang 26 seated in the handle. Tie arm 2l is preferably formed as a separate piece having an aperture engaging the axle, and also preferably having an outturned tang 21a. penetrating the end of the handle. The axle 2 has its outer end turned to form the arm 28. One end of cutting wire 8 is secured around the end of arm 23 as described in connection with Figures 1 and 3'; and the other end is clamped under ingers 29 stamped out of the tie arm 2l.

Figure 7 shows still another modification of my invention, comprising a frame having a handle portion 30 connected by spreader bars 3| to tie arms 32. In this case axle 33 is formed as a separate piece seated in suitable sockets formed in arms 32 and held by the taut cutting element 8. Guide roller 'l is `preferably journaled on a sleeve 34 clamped by a nut 36 threaded on a split end of the sleeve. An arm 31 is preferably secured to the other end of the sleeve and terminates in a forked portion 38 slidably engaging one of the spreader bars 3| of the frame. Graduations on the spreader bar facilitate setting the roller to a selected thickness of slice.

Iclaim:

1. A slicer comprising a handle, an axle terminating in a pointed end penetrating the handle, a laterally extending tie arm engaging the axle adjacent the handle and secured to the inner end of said handle, a second laterally extending tie arm at the other end 0f the axle, a guide roller journaled on the axle, and a cutting element connected to and extending between said arms.

2. A slicer comprising an axle, a pair of arms carried .by the axle and extending laterally therefrom in spaced relation, a cutting wire secured to and stretched taut between the arms, a sleeve slidable on the axle betweenthe arms and having slotted ends, collars for compressing the slotted ends of the sleeve into frictional engagement with the axle, and a guide roller journaled on the sleeve between said collars.

3. A slicer comprising an axle, a pair of arms carried by the axle and extending laterally therefrom in spaced relation, a cutting wire secured to and stretched taut between the arms, a sleeve slidable on the axle between the arms and having a slotted end with an annular groove transversely of the slot, a collar seated in the groove, and a guide roller journaled on the sleeve.
